1. General Physics

2. Force- Any Push or Pull
Receiver- Object getting the force
Agent- Object giving the force

3. Forces Balanced Forces- produce NO change in the motion of an object.
Unbalanced Forces- produce a change in the motion of the object.

4. Contact Force- force exerted by an agent that must touch the receiver.
Noncontact Force- force exerted by an agent that does not touch the receiver.

5. Types of Force
Electrical Force- force that causes unlike particles to attract and like particle to repel.
Elastic Force- force exerted by a material that is stretched.

6. Types of Force
Frictional Force- force exerted by two objects that rub together.
Types of friction- sliding, rolling, fluid

7. Centripetal Force- force that causes objects to move in a circular path.

8. Types of Forces
Buoyancy- the force pushing upwards by a liquid on a submerged body.
Magnetic Force- the attractive or repelling force of a magnet and/or iron

9. Types of Forces
Gravitational Force- the mutual force of attraction exerted by all objects.
Mass- amount of matter in an object
Weight- the amount of gravitational pull on an object.
